DUMP-WAGON.

To all whom it may concern:

Be it known that 1, WILLIAM E. SHER- WOOD, a citizen of the United States, and a resident of Canastota, in the county of Madison and State of New York, have invented a certain new and useful Dumpl/Vagon, of which the following is a specification.

This invention relates to dumping wagons and particularly to means for opening and closing the dumping sections or doors, which means is particularly simple in construction, highly ellicient and durable in use; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional view, partly broken away, and parts being revmoved, of a dumping wagon embodying my invention. Fig. 2 is a transverse sectional View on line AA, Fig. 1, parts being removed. Figs. 3 and l, are sectional views looking in opposite directions on a plane extending between the ratchet wheels of the drums. Fig. 5 is a detail view in plan of the holding pawls and contiguous parts. Fig. 6 is a fragmentary view illustrating in plan, the ratchet wheels, and the pawl carried by the end board of the box for holding either ratchet wheel whereby the doors can be dumped singly.

1 is the box of a dump wagon having a pair of dumping doors 2 hinged at their outer edges to the box. The doors 2 are controlled in their opening and closing movements by winding mechanism and means for holding the winding mechanism from retrograde movement. The winding mechanism is in this embodiment of my invention held from unwinding by means operable to release both doors simultaneously, and also by additional means operable to release the doors singly.

In the illustrated embodiment of my invention, the means for controlling the opening and closing of the doors 2 comprises a pair of drums 3, 4 and cables 5 winding on the drums respectively, and means for winding the drums. The cables 5 are connected at 6 and 7 to the drums and run under the Specification of Letters Patent.

connected to the rear end board 10 of the box 1n any suitable manner. The cables are here shown as engaging hooks as the hook 11 on the rear end board, but may be connected to The means for winding the drums 3, 1 includes ratchet wheels 12, 13 mounted respectively on the drums 3, l contiguous to each other and operating means coacting with the ratchet wheels to wind the same. The operating means consists of a lever arranged contiguous to the ratchet wheels 12, 13 and carrying a pawl of suflicient width to engage both ratchet wheels 12, 13 in order to wind both simultaneously, the pawl being shiftable out of engagement with either ratchet wheel 12, or 13 into sole engagement with the other whereby one door can be closed independently of the other or can be started toward its closed position ahead of the other, and, after it has been so started, both doors can then be closed together as when one door is formed with a batten strip that laps the other door.

In the illustrated form of my invention, the operating lever 14 extends between the ratchet wheels 12 and 13, and oscillates about the axis of the drums 3, 4-, and the pawl 15, which is wide enough to engage both ratchet wheels 12, 13, is carried at the lower end of a hand lever 16 pivoted between its ends at 17 to the operating lever, on a pivot extending in the direction of the oscillating movement of the lever 14:. For permitting ratcheting of the pawl 15, the operating lever 1-1 is formed with an elongated bearing 18 extending around the drum 4, this bearing being here shown as mounted on the hub 19 of the ratchet wheel 13. The hand lever 14- is guided in its shifting movement by any suitable means, as a strap 20 embracing the pawl 15 and arranged to limit the lateral shifting of the pawl 15 in either direction. If desired, suitable spring-pressed locking detents or plungers may be used to snap into engagement with the pawl 15 or lever 16, when the pawl is in either of its three operative positions, and this locking means may be carried by the strap 20.. During the oscillating movement of the lever 14 backwardly, obviously owing to the elongated with the ratchet wheels.

one ratchet wheel.

bearing 18, the levers 14 and 16 will move endwisely as the pawl 15 ratchets. Upon the forward movement of the levers 14 and 16, the ratchet Wheels 12, 13 will'be actuated if the pawl 15 is engaged with both.

after being wound up by pawls 24, 25 coacting with the ratchet wheels 12, 13 and pivoted at 26 to the short arm of a lever 27 which is pivoted at 28 between its ends to the neck 23 of the wagon body, the long arm of the lever 27 being engaged by a catch or trip lever 29 pivoted at 30 and having a pedal 31 by means of which it is operated forwardly to release the lever 27. The catch 29 is also formed with an arm 32 for engaging the long arm of the lever 27 by which the trip lever 29 is reset when the operator depresses the long arm of the lever 27 by engaging his foot with a pedal 27 on said lever. The long arm of the lever 27 is of sufficient length to have enough resiliency to permit the pawls 24 and 25 to ratchet, as the pawls are formed with shoulders which normally engage stops 27 on the level-'27 and hold the pawls from downward pivotal movement. Both of these pawls are provided with weights 33 which tend to hold the pawls with their points in engagement The lever 29 is tripped by pushing the pedal 31 forwardly to permit the long arm of the lever 27 to move upwardly and the short arm thereof forwardly and downwardly carrying the pivots of the pawls 24 and 25 below the dead center lines so that retrograde movement of the ratchet wheels causes the points of the pawls to be carried upwardly. The weights 33 return the pawls to their normal position relatively to the lever 27 The additional holding means for holding either door from moving downwardly while permitting of the movement of the com panion door, or for permitting both doors to move downwardly substantially simultaneously, includes a pawl 34 preferably mounted on the wagon body. As here shown, said pawl 24 cooperates with the ratchet wheels 12, 13 and holds onedrum from unwinding movement, and is supported by the front end board 35 of the boX and shiftable to engage either ratchet wheel 12 or 13, or into position to be out of engagement with both ratchet wheels. As here shown, the

pawl" 34 is slidable laterally on a shaft 36 carried on the front side of the front end board 35, in lugs 37.

In operation, if it is desired, to hold the door operated by the chain 5, which is connected to the drum 4, the pawl 34 is moved into engagement with the ratchet wheel 13 so that upon the operation of the trip lever 31 the drum 4 will be held from unwinding movement. If it is desired to hold the door 2 connected to the chain 5 which winds on the drum 3, the pawl 34 is shifted into engagement with the ratchet wheel 12 and if it is desired to dump both doors in the ordinary manner, the pawl 34 is shifted to one side of both ratchet wheels 12 and 13. When the doors are dumped singly, the box may be provided with a lengthwise partition 38.
